10 <para>As briefly mentioned in <xref linkend="frontends" />, VBoxManage is
11 the command-line interface to VirtualBox. With it, you can completely
12 control VirtualBox from the command line of your host operating system.
13 VBoxManage supports all the features that the graphical user interface
14 gives you access to, but it supports a lot more than that. It exposes
15 really all the features of the virtualization engine, even those that
16 cannot (yet) be accessed from the GUI.</para>
17
18 <para>You will need to use the command line if you want to</para>

20 <para><itemizedlist>

23 VBoxSDL or the VBoxHeadless server);</para>

27 <para>control some of the more advanced and experimental
28 configuration settings for a VM.</para>
29 </listitem>
30 </itemizedlist></para>
31
32 <para>There are two main things to keep in mind when using
33 <computeroutput>VBoxManage</computeroutput>: First,
34 <computeroutput>VBoxManage</computeroutput> must always be used with a
35 specific "subcommand", such as "list" or "createvm" or "startvm". All the
36 subcommands that <computeroutput>VBoxManage</computeroutput> supports are
37 described in detail in <xref linkend="vboxmanage" />.</para>
38
39 <para>Second, most of these subcommands require that you specify a
40 particular virtual machine after the subcommand. There are two ways you
41 can do this:</para>
42
43 <itemizedlist>
44 <listitem>
45 <para>You can specify the VM name, as it is shown in the VirtualBox
46 GUI. Note that if that name contains spaces, then you must enclose the
47 entire name in double quotes (as it is always required with command
48 line arguments that contain spaces).</para>
49
50 <para>For example:<screen>VBoxManage startvm "Windows XP"</screen></para>
51 </listitem>
52
53 <listitem>
54 <para>You can specify the UUID, which is the internal unique
55 identifier that VirtualBox uses to refer to the virtual machine.
56 Assuming that the aforementioned VM called "Windows XP" has the UUID
57 shown below, the following command has the same effect as the
58 previous:<screen>VBoxManage startvm 670e746d-abea-4ba6-ad02-2a3b043810a5</screen></para>
59 </listitem>
60 </itemizedlist>
61
62 <para>You can type <computeroutput>VBoxManage list vms</computeroutput> to
63 have all currently registered VMs listed with all their settings,
64 including their respective names and UUIDs.</para>
65
66 <para>Some typical examples of how to control VirtualBox from the command
67 line are listed below:</para>
68
69 <itemizedlist>
70 <listitem>
71 <para>To create a new virtual machine from the command line and
72 immediately register it with VirtualBox, use
73 <computeroutput>VBoxManage createvm</computeroutput> with the
74 <computeroutput>--register</computeroutput> option,<footnote>
75 <para>For details, see <xref
76 linkend="vboxmanage-createvm" />.</para>

302
303 <para>The <computeroutput>registervm</computeroutput> command allows you
304 to import a virtual machine definition in an XML file into VirtualBox. The
305 machine must not conflict with one already registered in VirtualBox and it
306 may not have any hard or removable disks attached. It is advisable to
307 place the definition file in the machines folder before registering
308 it.<note>
309 <para>When creating a new virtual machine with
310 <computeroutput>VBoxManage createvm</computeroutput> (see below), you

347
348 <para>This command creates a new XML virtual machine definition
349 file.</para>
350
351 <para>The <computeroutput>--name &lt;name&gt;</computeroutput> parameter
352 is required and must specify the name of the machine. Since this name is
353 used by default as the file name of the settings file (with the extension
354 <computeroutput>.xml</computeroutput>) and the machine folder (a subfolder
355 of the <computeroutput>.VirtualBox/Machines</computeroutput> folder), it
356 must conform to your host operating system's requirements for file name
357 specifications. If the VM is later renamed, the file and folder names will
358 change automatically.</para>
359
360 <para>However, if the <computeroutput>--basefolder
361 &lt;path&gt;</computeroutput> option is used, the machine folder will be
362 named <computeroutput>&lt;path&gt;</computeroutput>. In this case, the
363 names of the file and the folder will not change if the virtual machine is
364 renamed.</para>
365
366 <para>By default, this command only creates the XML file without
367 automatically registering the VM with your VirtualBox installation. To
368 register the VM instantly, use the optional
369 <computeroutput>--register</computeroutput> option, or run
370 <computeroutput>VBoxManage registervm</computeroutput> separately
371 afterwards.</para>

375 <title>VBoxManage modifyvm</title>
376
377 <para>This command changes the properties of a registered virtual machine
378 which is not running. Most of the properties that this command makes
379 available correspond to the VM settings that VirtualBox graphical user
380 interface displays in each VM's "Settings" dialog; these were described in
381 <xref linkend="BasicConcepts" />. Some of the more advanced settings,
382 however, are only available through the
383 <computeroutput>VBoxManage</computeroutput> interface.</para>
384
385 <para>These commands require that the machine is powered off (neither
386 running nor in "saved" state). Some machine settings can also be changed
387 while a machine is running; those settings will then have a corresponding
388 subcommand with the <computeroutput>VBoxManage controlvm</computeroutput>

1046 imported into VirtualBox, together with the optional command-line options
1047 to influence the import behavior.</para>
1048
1049 <para>As an example, here is the screen output with a sample appliance
1050 containing a Windows XP guest:<screen>VBoxManage import WindowsXp.ovf --dry-run
1051Interpreting WindowsXp.ovf...
1052OK.

1069 (change with "--vsys 0 --unit 9 --scsitype {BusLogic|LsiLogic}";
1070 disable with "--vsys 0 --unit 9 --ignore")

1075 (change controller with "--vsys 0 --unit 11 --controller &lt;id&gt;";
1076 disable with "--vsys 0 --unit 11 --ignore")</screen></para>
1077
1078 <para>As you can see, the individual configuration items are numbered, and
1079 depending on their type support different command-line options. The import
1080 subcommand can be directed to ignore many such items with a
1081 <computeroutput>--vsys X --unit Y --ignore</computeroutput> option, where
1082 X is the number of the virtual system (zero unless there are several
1083 virtual system descriptions in the appliance) and Y the item number, as
1084 printed on the screen.</para>
1085
1086 <para>In the above example, Item #1 specifies the name of the target
1087 machine in VirtualBox. Items #9 and #10 specify hard disk controllers,
1088 respectively. Item #11 describes a hard disk image; in this case, the
1089 additional <computeroutput>--controller</computeroutput> option indicates
1090 which item the disk image should be connected to, with the default coming
1091 from the OVF file.</para>
1092
1093 <para>You can combine several items for the same virtual system behind the
1094 same <computeroutput>--vsys</computeroutput> option. For example, to
1095 import a machine as described in the OVF, but without the sound card and
1096 without the USB controller, and with the disk image connected to the IDE
1097 controller instead of the SCSI controller, use this:<screen>VBoxManage import WindowsXp.ovf
1098 --vsys 0 --unit 5 --ignore --unit 6 --ignore --unit 11 --controller 10</screen></para>

1102 <title>VBoxManage export</title>
1103
1104 <para>This command exports one or more virtual machines from VirtualBox
1105 into a virtual appliance in OVF format, including copying their virtual
1106 disk images to compressed VMDK. See <xref linkend="ovf" /> for an
1107 introduction to appliances.</para>
1108
1109 <para>The <computeroutput>export</computeroutput> command is simple to
1110 use: list the machine (or the machines) that you would like to export to
1111 the same OVF file and specify the target OVF file after an additional
1112 <computeroutput>--output</computeroutput> or
1113 <computeroutput>-o</computeroutput> option. Note that the directory of the
1114 target OVF file will also receive the exported disk images in the
1115 compressed VMDK format (regardless of the original format) and should have
1116 enough disk space left for them.</para>
1117
1118 <para>Beside a simple export of a given virtual machine, you can append
1119 several product information to the appliance file. Use
1120 <computeroutput>--product</computeroutput>,
1121 <computeroutput>--producturl</computeroutput>,
1122 <computeroutput>--vendor</computeroutput>,
1123 <computeroutput>--vendorurl</computeroutput> and
1124 <computeroutput>--version</computeroutput> to specify this additional
1125 information. For legal reasons you may add a license text or the content
1126 of a license file by using the <computeroutput>--eula</computeroutput> and
1127 <computeroutput>--eulafile</computeroutput> option respectively. As with
1128 OVF import, you must use the <computeroutput>--vsys X</computeroutput>
1129 option to direct the previously mentioned options to the correct virtual
1130 machine.</para>
1131
1132 <para>For virtualization products which aren't fully compatible with the
1133 OVF standard 1.0 you can enable a OVF 0.9 legacy mode with the

1352 <title>VBoxManage snapshot</title>
1353
1354 <para>This command is used to control snapshots from the command line. A
1355 snapshot consists of a complete copy of the virtual machine settings,
1356 copied at the time when the snapshot was taken, and optionally a virtual
1357 machine saved state file if the snapshot was taken while the machine was
1358 running. After a snapshot has been taken, VirtualBox creates differencing
1359 hard disk for each normal hard disk associated with the machine so that
1360 when a snapshot is restored, the contents of the virtual machine's virtual
1361 hard disks can be quickly reset by simply dropping the pre-existing
1362 differencing files.</para>
1363
1364 <para>The <computeroutput>take</computeroutput> operation takes a snapshot
1365 of the current state of the virtual machine. You must supply a name for
1366 the snapshot and can optionally supply a description. The new snapshot is
1367 inserted into the snapshots tree as a child of the current snapshot and
1368 then becomes the new current snapshot.</para>
1369
1370 <para>The <computeroutput>delete</computeroutput> operation deletes a
1371 snapshot (specified by name or by UUID). This can take a while to finish
1372 since the differencing images associated with the snapshot might need to
1373 be merged with their child differencing images.</para>
1374
1375 <para>The <computeroutput>restore</computeroutput> operation will restore
1376 the given snapshot (specified by name or by UUID) by resetting the virtual
1377 machine's settings and current state to that of the snapshot. The previous
1378 current state of the machine will be lost. After this, the given snapshot
1379 becomes the new "current" snapshot so that subsequent snapshots are
1380 inserted under the snapshot from which was restored.</para>
1381
1382 <para>The <computeroutput>restorecurrent</computeroutput> operation is a
1383 shortcut to restore the current snapshot (i.e. the snapshot from which the
1384 current state is derived). This subcommand is equivalent to using the
1385 "restore" subcommand with the name or UUID of the current snapshot, except
1386 that it avoids the extra step of determining that name or UUID.</para>
1387
1388 <para>With the <computeroutput>edit</computeroutput> operation, you can
1389 change the name or description of an existing snapshot.</para>
1390

2037
2038 <para>The <computeroutput>usbfilter</computeroutput> commands are used for
2039 working with USB filters in virtual machines, or global filters which
2040 affect the whole VirtualBox setup. Global filters are applied before
2041 machine-specific filters, and may be used to prevent devices from being
2042 captured by any virtual machine. Global filters are always applied in a
2043 particular order, and only the first filter which fits a device is
2044 applied. So for example, if the first global filter says to hold (make
2045 available) a particular Kingston memory stick device and the second to
2046 ignore all Kingston devices, that memory stick will be available to any
2047 machine with an appropriate filter, but no other Kingston device
2048 will.</para>
2049
2050 <para>When creating a USB filter using <computeroutput>usbfilter
2051 add</computeroutput>, you must supply three or four mandatory parameters.
2052 The index specifies the position in the list at which the filter should be
2053 placed. If there is already a filter at that position, then it and the
2054 following ones will be shifted back one place. Otherwise the new filter
2055 will be added onto the end of the list. The
2056 <computeroutput>target</computeroutput> parameter selects the virtual
2057 machine that the filter should be attached to or use "global" to apply it
2058 to all virtual machines. <computeroutput>name</computeroutput> is a name
2059 for the new filter and for global filters,
2060 <computeroutput>action</computeroutput> says whether to allow machines
2061 access to devices that fit the filter description ("hold") or not to give
2062 them access ("ignore"). In addition, you should specify parameters to
2063 filter by. You can find the parameters for devices attached to your system
2064 using <computeroutput>VBoxManage list usbhost</computeroutput>. Finally,
2065 you can specify whether the filter should be active, and for local
2066 filters, whether they are for local devices, remote (over an RDP
2067 connection) or either.</para>
2068
2069 <para>When you modify a USB filter using <computeroutput>usbfilter
2070 modify</computeroutput>, you must specify the filter by index (see the
2071 output of <computeroutput>VBoxManage list usbfilters</computeroutput> to
2072 find global filter indexes and that of <computeroutput>VBoxManage
2073 showvminfo</computeroutput> to find indexes for individual machines) and
2074 by target, which is either a virtual machine or "global". The properties
2075 which can be changed are the same as for <computeroutput>usbfilter

2082
2083 <para>This command allows you to share folders on the host computer with
2084 guest operating systems. For this, the guest systems must have a version
2085 of the VirtualBox Guest Additions installed which supports this
2086 functionality.</para>

2093 <title id="metrics">VBoxManage metrics</title>
2094
2095 <para>This command supports monitoring the usage of system resources.
2096 Resources are represented by various metrics associated with the host
2097 system or a particular VM. For example, the host system has a
2098 <computeroutput>CPU/Load/User</computeroutput> metric that shows the
2099 percentage of time CPUs spend executing in user mode over a specific
2100 sampling period.</para>
2101
2102 <para>Metric data is collected and retained internally; it may be
2103 retrieved at any time with the <computeroutput>VBoxManage metrics
2104 query</computeroutput> subcommand. The data is available as long as the
2105 background <computeroutput>VBoxSVC</computeroutput> process is alive. That
2106 process terminates shortly after all VMs and frontends have been
2107 closed.</para>
2108
2109 <para>By default no metrics are collected at all. Metrics collection does
2110 not start until <computeroutput>VBoxManage metrics setup</computeroutput>
2111 is invoked with a proper sampling interval and the number of metrics to be
2112 retained. The interval is measured in seconds. For example, to enable
2113 collecting the host processor and memory usage metrics every second and
2114 keeping the 5 most current samples, the following command can be
2115 used:</para>
2116
2117 <screen>VBoxManage metrics setup --period 1 --samples 5 host CPU/Load,RAM/Usage</screen>
2118
2119 <para>Metric collection can only be enabled for started VMs. Collected
2120 data and collection settings for a particular VM will disappear as soon as
2121 it shuts down. Use <computeroutput>VBoxManage metrics list
2122 </computeroutput> subcommand to see which metrics are currently available.
2123 You can also use <computeroutput>--list</computeroutput> option with any
2124 subcommand that modifies metric settings to find out which metrics were
2125 affected.</para>
2126
2127 <para>Note that the <computeroutput>VBoxManage metrics
2128 setup</computeroutput> subcommand discards all samples that may have been
2129 previously collected for the specified set of objects and metrics.</para>
2130
2131 <para>To enable or disable metrics collection without discarding the data
2132 <computeroutput>VBoxManage metrics enable</computeroutput> and
2133 <computeroutput>VBoxManage metrics disable</computeroutput> subcommands
2134 can be used. Note that these subcommands expect metrics, not submetrics,
2135 like <code>CPU/Load</code> or <code>RAM/Usage</code> as parameters. In
2136 other words enabling <code>CPU/Load/User</code> while disabling
2137 <code>CPU/Load/Kernel</code> is not supported.</para>
2138
2139 <para>The host and VMs have different sets of associated metrics.
2140 Available metrics can be listed with <computeroutput>VBoxManage metrics
2141 list</computeroutput> subcommand.</para>
2142
2143 <para>A complete metric name may include an aggregate function. The name
2144 has the following form:
2145 <computeroutput>Category/Metric[/SubMetric][:aggregate]</computeroutput>.
2146 For example, <computeroutput>RAM/Usage/Free:min</computeroutput> stands
2147 for the minimum amount of available memory over all retained data if
2148 applied to the host object.</para>
2149
2150 <para>Subcommands may apply to all objects and metrics or can be limited
2151 to one object or/and a list of metrics. If no objects or metrics are given
2152 in the parameters, the subcommands will apply to all available metrics of
2153 all objects. You may use an asterisk
2154 ("<computeroutput>*</computeroutput>") to explicitly specify that the
2155 command should be applied to all objects or metrics. Use "host" as the
2156 object name to limit the scope of the command to host-related metrics. To
2157 limit the scope to a subset of metrics, use a metric list with names
2158 separated by commas.</para>
2159
2160 <para>For example, to query metric data on the CPU time spent in user and
2161 kernel modes by the virtual machine named "test", you can use the
2162 following command:</para>
2163
2164 <screen>VBoxManage query test CPU/Load/User,CPU/Load/Kernel</screen>

2254 guest or the host, so they can be used as a low-volume communication
2255 channel for strings, provided that a guest is running and has the Guest
